Re: [Gluster-users] ACL issue v6.6, v6.7, v7.1, v7.2

Hi, this is interesting, this happen always with gluster 6.6 or only in certain cases? I ask this because I have two ovirt clusters with gluster, both with gluster v6.6, in one case I've upgraded from 6.5 to 6.6 as Strahil, and I haven't hit this bug. When upgrading my clusters I follow exactly the steps reported by Strahil in the bug report, some other things should be different.

OVN issues: no connectivity between VMs on same host
by thkam＠hua.gr 07 Feb '20

07 Feb '20

Hi I am getting some problems setting up an internal networks for our oVirt VMs using the OVN external provider. The ovn-provider was setup during the ovirt engine installation (version 4.3.7.2-1.el7). I then just created a new network with the ovn external provider and tested the connectivity using the corresponding button on the oVirt UI. Two of my VMs are Ubuntu 18.04 servers with ips 10.0.0.101 and 10.0.0.102 with gateways 10.0.0.102 and 10.0.0.101 respectively. So I guess under normal circumstances they should be able to ping each other. I tried disabling the firewalld service on both the host and the ovirtengine but still nothing changed. However I noticed something odd on the firewalld status on the host. With firewalld enabled, I get: [root@ovirt7 ~]# systemctl status firewalld ● firewalld.service - firewalld - dynamic firewall daemon Loaded: loaded (/usr/lib/systemd/system/firewalld.service; enabled; vendor preset: enabled) Active: active (running) since Πεμ 2020-02-06 06:10:38 UTC; 14s ago Docs: man:firewalld(1) Main PID: 4436 (firewalld) Tasks: 2 CGroup: /system.slice/firewalld.service └─4436 /usr/bin/python2 -Es /usr/sbin/firewalld --nofork --nopid Φεβ 06 06:10:39 ovirt7.hua.gr firewalld[4436]: WARNING: COMMAND_FAILED: '/usr/sbin/ebtables --concurrent -t nat -D POSTROUTING -o vnet1 -j libvirt-O-vnet1' failed: Illegal target name 'libvirt-O-vnet1'.

Websocket-proxy not working after upgrade to 4.3

Hi, We recently upgraded to 4.3.8 and everything is working fine but the VNC Console (Browser). Once I click on "VNC Console (Browser)" on any machine from the VM Portal, I get a message like this: Disconnected from Console Cannot connect to websocket proxy server.

Backup Solution
by Christian Reiss 07 Feb '20

07 Feb '20

Hey folks, Running a 3-way HCI (again (sigh)) on gluster. Now the _inside_ of the vms is backup'ed seperatly using bareos on an hourly basis, so files are present with worst case 59 minutes data loss. Now, on the outside I thought of doing gluster snapshots and then syncing those .snap dirs away to a remote 10gig connected machine on a weekly-or-so basis. As those contents of the snaps are the oVirt images (entire DC) I could re-setup gluster and copy those files back into gluster and be done with it. Now some questions, if I may: - If the hosts remain intact but gluster dies, I simply setup Gluster, stop the ovirt engine (seperate standalone hardware) copy everything back and start ovirt engine again. All disks are accessible again (tested). The bricks are marked as down (new bricks, same name). There is a "reset brick" button that made the bricks come back online again. What _exactly_ does it do? Does it reset the brick info in oVirt or copy all the data over from another node and really, really reset the brick? - If the hosts remain intact, but the engine dies: Can I re-attach the engine the the running cluster? - If hosts and engine dies and everything needs to be re-setup would it be possible to do the setup wizard(s) again up to a running point then copy the disk images to the new gluster-dc-data-dir? Would oVirt rescan the dir for newly found vms? - If _one_ host dies, but 2 and the engine remain online: Whats the oVirt way of resetting up the failed one? Reinstalling the node and then what? From all the cases above this is the most likely one. Having had to reinstall the entire Cluster three times already scares me. Always gluster related. Again thank you community for your great efforts! -- with kind regards, mit freundlichen Gruessen, Christian Reiss

Huge increase of CPU load on hosted engine VM after upgrade to 4.3.8 and cluster compatibility version
by Florian Schmid 06 Feb '20

06 Feb '20

Hi, I have upgraded yesterday one of our ovirt environments from 4.2.8 to 4.3.8. We have a hosted engine, 25 hosts and about 150 VMs running there. After upgrading the cluster compatibility version from 4.2 to 4.3, I have seen a huge increase of CPU load on the engine VM. The engine had 4 cores (16GB mem) and never had load issues, but after the upgrade, the system has a load of 6 and more. I have increased the CPUs to 8, because working in the UI was impossible. I have noticed, that the load always increase, when I load the VM UI tab, where now all VMs have the orange triangle with pending changes: Custom compatibility version The problem I have, is, that I can't reboot now all VMs, maybe in the next 3 or 4 weeks. Working now with the UI is quite problematic, because of the slowness. The engine VM was already rebooted, but didn't solve the problem. What logs do you need and is there a workaround available? I have some more oVirt environments to upgrade, all with even more VMs. BR Florian

oVirt MAC Pool question
by Vrgotic, Marko 06 Feb '20

06 Feb '20

Dear oVirt, While investigating and DHCP & DDNS collision issues between two VM servers from different oVirt clusters, I noticed that oVirt assigns same default MAC range for each of it’s managed clusters. Question1: Does oVirt-Engine keep separate place in DB or … for MAC addresses assigned per cluster or it keeps them all in same place? Question2: Would there be an harming effect on existing VMs if the default mac pool would be changed? Additional info: Self Hosted ovirt-engine – 4.3.4 and 4.3.7 ----- kind regards/met vriendelijke groeten Marko Vrgotic ActiveVideo

Single-Host Hyperconverged set-up not showing gluster volumes
by Guillaume Pavese 05 Feb '20

05 Feb '20

Hi, I setup a new oVirt hosted engine instance on a mono-server DC/Cluster; I deployed gluster on the Hypervisor with cockpit and then the hosted engine with hosted-engine --deploy It seems to be working, but IO perfs are not good (10MB/s) on a 4x SAS disks raid5. So I wanted to check if the optimize for virt-store settings had been applied (I remember that there used to be a bug for at least most of 4.2.x) However, event if I see the data domains in "Storage >> Storage Domains" and in "Storage >> Data Centers", "Storage >> Volumes" is empty. Is that normal? Any idea if there is anything to do to see the gluster volumes there and manage theirs options?

memory overcommit in oVirt
by yam yam 04 Feb '20

04 Feb '20

Hello, I thought memory overcommit feature in oVirt utilizes host's overcommit features by manipulating kernel variables like vm.overcommit_ratio, vm_overcommit_memory. but, I've just confirmed that those variables didn't change at all. I wonder if oVirt's overcommit really has nothing to do with that of host and if so, how does oVirt manage memory overcommit.

ESXi 6.7 as a nested VM on top of oVirt cluster.
by branimirp＠gmail.com 03 Feb '20

03 Feb '20

Hello list I am wondering if anyone has tried this before? I am trying to consolidate my lab to an oVirt cluster which consists of oVirt (4.3.8) and 2 KVM hypervisors (CentOS 7.7.). Among other things, one of my efforts is a small ESXi + vCenter lab. In addition, I have a standalone KVM hypervisor. I can run nested ESXi 6.7 on top of the standalone KVM hypervisor (with nested KVM enabled) without any problem. However, on top of oVirt-controlled KVMs I have some issues. The hypervisors have nested kvm support enabled via vdsm hooks. qemu emulates e1000 for a nested ESXi vm. ESXi installation process goes smooth but as soon as I enable management network and restart it, the nested ESXi cannot communicate with the outside world (DNS ping cannot pass). Also https connection to VMWare ESXi web gui and ping to the ESXi also fail. I noticed on my client machine, that ARP requests are incomplete for ESXI as well. Within oVirt, I see no packet drops in "Network interface" tab for the nested ESXi. In addition, I have a few, ordinary, non-nested VMs running on the same network as the nested vm and I can normally establish connection to those machines. Additionally, as a test, I created a nested KVM vm on top of the oVirt cluster, same network as the nested ESXi and it works as expected - can spin VMs, can connect to it. The network assigned to the nested ESXi has a "No network filter" vNic profile applied. I tried to google for a solution but found only this: https://github.com/mechinn/kvmhidden - not sure if this is the solution at all (also, I wonder if this is still up-to-date after 3+ years)? Could I please ask if anyone tried something similar and experienced this problem? Is there any additional configuration that I should apply to the oVirt cluster? Thank you very much in advance! Regards, Branimir
